PATENT OFFICE C YLINDRICAL DRUM TUMBLER USED 1N THE PROCESS OF MIXINGPAINT Alfred C. Sc hmohl, Beaver Falls, Pa assignor to V KoppelIndustrial Car and Equipment Company, Koppel, Pa., a corporation ofPennsyl- Vania Application October 26, 1932, Serial No. 639,665 r 2Claims. .25941) j ing wheels ll, said wheels being suitably keyed Thisinvention relates to drum tumblers and more particularly to that type oftumbler which is used in the mixing of pigment and a liquid in themanufacture of paint after said pigment and liquid has been placed intoa cylindrical drum or any other suitable container.

One of the objects of the invention is the rotation of the drum uponsuitably spaced wheels thereby agitating the pigment and liquid so as tothoroughly mix them for commercial use; 1

Another object of this invention is to accelerate the agitating motionof the cylindrical drums so as to efifect the quicker mixing of thecontained ingredients. i A further object of the invention is to arrangethe agitating wheels in such'a manner so as to setup an oscillatingmotion within the thereupon mounted cylindrical drum.

Other objects will become apparent to those skilled in the art from theaccompanying drawing which forms a part of the present description; inwhich Fig. 1 shows, in side elevation, an arrangement of parts thatconstitutethe drum tumbler of the present invention comprised of a baseframe, agitator wheels mounted upon the base frame having a cylindricaldrum resting thereon and the motive powerfor the rotation of saidwheels.

Fig. 2 is a plan View of the drum tumbler shown in Fig. 1. I r

Fig. 3 is a sectional view taken along line 3-3 of Fig. 2 showing moreclearly the arrangement of the agitator wheels andytheir relation to thecylindrical drum.

Fig. 4 shows a modification in the tread portion of the agitator wheels.

Referring now in detail to the. drawing where like reference charactersrefer to like parts, the base frame I is composed of two oppositelydisposed horizontal angles 2 fastened together at their extremities byangular plates 3. Depending from each corner of the structure thusformed are vertical standards 4 having angular clips 5 secured to theirfree ends to form feet, affording an enlarged bearing area to supportthe base frame. Adjacent the lower extremities and. secured to thevertical standards are horizontal angular members 6 which add rigidityto the base frame and support a motor I and gear case 8 hereinafterreferred to.

Mounted upon the base frame are a pair of journaled axles 9 anchoredthereupon by stirrups Hi. The axles are so spaced longitudinally of thebase frame so as to allow a cylindrical drum l3 to be supported upon andbetween the agitated adjacent the journal boxes.

of the wheels of a pair. both gears on the pair of axles in order thatthe to the extremities of each of theaxles and mount-. The agitatingwheels have flanges [2 along their outer edge in order that a drumrevolving thereupon will be held within the limits of the flanges andthereby retained upon the wheels. The cylindrical drums are placed inposition on the wheels and removed 7 therefrom by any suitable means;they being so handled in the present case by means of a skid (not shown)which is supported by and pivoted about the bar l1, said bar beingspaced from the base frame by brackets l8.

The gear 16 mounted on the shaft projecting from the gear case 8, whichis driven by the motor 1 adjacent thereto, engages anendless chain 22which in turn engages a gear I 9 suitably mounted upon each journaledaxle adjacent at least one The chain 22 engages wheels will alwaysmaintain the same relation to each other and thereby afford a morepositive action of mixing, and accelerate the agitating motion impartedto the ingredients contained within the cylindrical drum.

arranged so as to be in staggered relation with respect'to the drum andcoincidental with respect to each pair of wheels. The drum I3 beingrotated upon and between the wheels, which have their peripheries soindented and the indentures so arranged, will alternately ride upon thetrue circumferences ii of the wheel and the indentures l4. When acylindrical drum is in contact with the surface of the truecircumference of the forward pair of wheels it will be resting on theindented portion of the other pair of wheels and thisarrangement of truecircumferential surfaces and indentures will alternate their positionsupon the further rotation of the wheels. The alternate positioning ofthe indentures and true cir- If it is so desired wheels 20 withcam-shaped treads as shown in Fig. 4 can be substituted for the agitatorwheels I I which will impart the same action to the cylindrical drums.Crank 2 f, shown in dot and dash lines in Figs. 1 and 2, may be keyed toone of the axles in order that the agitating wheels may be propelled bymanual power if it is so preferred. 7

It will be apparent to one skilled in the art that the constructionshown on the drawing may be modified to the extent that the chain 22 maybe arranged to engage but one gear I9. By this modification motion willbe imparted from the driving axle to the other axle 9 through the druml3.

Having thus described the invention what I claim as new and desire tosecure by Letters Patent is 7 1. In a mechanism of the characterdescribed,

a pair of spaced driving shafts, agitating members secured in spacedrelation adjacent each end of each shaft and adapted to support acylindrical container, each of said agitating members bein provided witha generally circular outer surface having radially spaced indentures' toimpart spaced impacts to the container and each shaft having itsagitating members mounted to present a peripheral and indented surfacesimultaneously to opposite ends of the container and means impartingrotary movement to each shaft.

2. In a device of the character described, a base frame, transverserotary axles journaled in longitudinal spaced relation on theframe,wheel shaped members comprising a container supporting tread ofgeneral circular form having radially spaced indentures and a flange atone, side of the tread, two of said wheel shaped members being fixed toeach axle with the tread portions directed inwardly from the ends of theaxles and an indenture of the tread of one member opposite anunindentured surface of the tread of the opposing member, and means forimparting rotary, movement to said members."
